Question

I'm a bit confused on how to get this program to run right. Here are the directions:

Part 1: Write a Python function called reduceWhitespace that is given a string line and returns the line with all extra whitespace characters between the words removed. For example, ‘This line has extra space characters ‘  ‘This line has extra space characters’

Function name: reduceWhitespace

Number of parameters: one string line

Return value: one string line

The main file should handle the file operations to read from a .txt file you create and call the function from the module you create. In main you should also print out your text from the file before the function call and print the result after the function call, showing that the function works. Additionally, write the lines with reduce whitespaces into a text file. Your function should also include the specification (docstring). Note: I will test your file by giving it a .txt file I create, so you should prompt the user for the text file (the framework for that is provide to you inside the main file).

Lab 9 Part 2: In the same module, write a Python function named countAllLetters that is given a string line and returns a list containing every letter and character in the line and the number of times that each letter/character appears (with upper/lower case letters counted together). For example, ‘This is a short line’  [(‘t’,2), (‘h’,2), (‘i’,3), (‘s’,3), (‘ ‘,4), (‘a’,1), (‘o’,1), (‘r’,1), (‘l’,1), (‘n’,1), (‘e’,1)]

Function name: countAllLetters

Number of parameters: one string line

Return value: a list

The main file should handle the file operations to read from a new .txt file you create and call the function from the module you create. In main, you should print out the text you read from the file, then call the function and then print out the resulting list, showing that the function works. You do not need to write the output into a text file. Your function should also include the specification (docstring). Note: I will test your file by giving it a .txt file I create, so you should prompt the user for the text file. Please zip both files and submit them as Lab9lastname.zip on Canvas. Please make sure you use the framework and follow the steps to complete the lab9main.py.

Here is what i have for both files:

def main():
  
filename1 = input('What is the textfile name without .txt: ') + '.txt'
filename2 = 'result' + filename1
fileIn = open(filename1, 'r')
fileOut = open('out.text', 'w')
for line in fileIn:
print('reduceWhitespace()')
print(line)
print('Reduced line is: ')
print(reducedLine)
fileOut.write(reducedLine + '\n')
  
print('#'*60)
print()
  
filename1 = input('what is the textfile name without .txt: ') + '.txt'
print('countAllLetters():')
print(line)
letters_count = countAllLetters(line)
print(letters_count)

main()

The second one:

def reduceWhitespace(line):
tokens = str(line).split()
splitline = str()
for item in tokens:
redicedLine = reducedLine + item + ' '
return reducedLine

def countAllLetters(line):
line= str(line).lower()
chars = []
letterCount = list()
for token in line.split():
for c in token:
if chars.count(c) == 0:
chars.append(c)
for c in chars:
letterCount.append((c,line.count(c)))
return letterCount
  

Answer 1

Here is the modified program: Save it in file main.py and run.

def reduceWhitespace(line):
return " ".join(line.split())

def countAllLetters(line):
tmpdict={}
retlist=[]
for s in line:
s = s.lower()
if s in tmpdict:
tmpdict[s] = tmpdict[s] + 1
else:
tmpdict[s] = 1
  
for key in tmpdict:
retlist.append((key,tmpdict[key]))
return retlist
  

def main():
  
filename1 = input('What is the textfile name without .txt: ') + '.txt'
filename2 = 'result' + filename1
fileIn = open(filename1, 'r')
fileOut = open('out.text', 'w')
for line in fileIn:
reducedLine = reduceWhitespace(line)
print(line)
print('Reduced line is: ')
print(reducedLine)
fileOut.write(reducedLine + '\n')
  
print('#'*60)
print()

line = "This is a short line"
print(line)
letters_count = countAllLetters(line)
print(letters_count)

main()
